Organisms

When you study organisms in a science fair project you need to use humane methods. This is a factor that is easy to forget when working with insects and spiders.

Test bacteria on any surface with the Surface Microbes Science Fair Projects Kit: after hand sanitizer, hands, disinfectant.. for example. You can use antibiotics to test the bacteria too.

Anytime you want to test how many bacteria are On Top of a surface like a desk, skin, chicken, computer keyboard, bread dough, a hard piece of chocolate, cheese, inside of an animal's cheek, etc. then use the surface experimenter kit. The kit will let you calculate how many bacteria there are per unit surface area on the object. You can also test for e-coli, however, only the microbe water kit will let you distinguish e. coli from other coliforms and bacteria.

 

Objectives/Goals

For my experiment I wanted to see if I could increase or decrease the brightness of the dinoflagelates and the amount of time they glowed for by changing the amount of light vs. darkness in the dinoflagelates circadian rhythm.

Methods/Materials

I had five different groups which had different amounts of light vs. dark. The different amounts of light were: always light; always dark; 6 hours light 18 hours dark; 18 hours light and 6 hours dark; and my control which was 12 hours light 12 hours dark.

Every other day I stirred the dinoflagellates using an apparatus that I made and recorded the amount of light they gave off using a scale I made from one to ten and I also measured the length of time they glowed for. I did this over a course of fourteen days.

Results

The data I gathered showed my control 12 hours light and 12 dark was a lot brighter and stayed light for longer than all of the other groups.

Conclusions/Discussion

My hypothesis was incorrect. I thought that the dinoflagelates with more light would glow brighter and stay light for longer. Instead my control of 12 hours light and 12 dark was the brightest group and they stayed alight the longest.

Overall my results show that not varying the circadian rhythm of the dinoflagelates and keeping them on their normal light cycle is better than adding or taking away light. 3rd party contributor
